Abstract
The utility model discloses a kind of frocks being used for rotor in magneto and lower bearing assembling, including axis body, threaded joints and the prismoid section with small end face and large end face, the left end of the axis body is fixedly connected with the small end face of prismoid section, and threaded joints are fixedly connected on the circle centre position of large end face in prismoid section；It is equipped with to be clamped the first card slot of driving plate on axis body.The utility model can ensure in rotor coaxial heart press-in lower bearing, avoid due to rotor displacement rotor being caused to collide with lower bearing, therefore can damaging rotor or lower bearing.
Description
Technical field：
The utility model is related to a kind of frocks being used for rotor in magneto and lower bearing assembling.
Background technology：
When magneto installs rotor, due to the attraction of rotor 200 and stator 300, rotor and bearing inner race (upper bearing (metal)
400 with lower bearing 500) orientation problem it is often more intractable, once rotor 200 and bearing inner race generate collision, it is likely that
Bearing can be damaged, for angular contact bearing.
For ease of installation, after existing assembling scheme typically first assembles rotor and the bearing of certain one end in place, then into
The installation of another end bearing of row.I.e.：
1) rotor 200 first assembles rotor 200, upper bearing (metal) 400, top chock and upper end cover before stator 300 is inserted into
It is fixed, it is ensured that with upper bearing (metal) 400 relative motion will not occur for rotor 200；2) then, by lower bearing 500, bottom end cover 600 and
Step is assemblied on motor case.3) lift again 1) in complete assembling rotor 200, upper bearing (metal) 400, top chock and
Motor upper cover component makes rotor 200 complete to assemble with lower bearing 500, such as Fig. 1 through stator 300.Due to rotor 200 with
The assembling of upper and lower bearing is higher to positioning accuracy request, and above-mentioned three steps installation method can need essence simultaneously to avoid bearings at both ends
Determine the situation of position.
However during the existing assembling rotor using aforesaid way, due between rotor 200 and stator 300 there are gap, because
During this rotor 200 press-in lower bearing 500, it is impossible under completion ensures that the axis direction of rotor 200 along lower bearing 500 enters
In bearing 500, once shifting, due to the magnetic force of rotor 200, then rotor 200 can be caused to collide with lower bearing 500,
It therefore can damaging rotor 200 or lower bearing 500.
Utility model content：
The utility model is provided a kind of for will be in magneto to solve the above-mentioned problems of the prior art
Rotor and the frock of lower bearing assembling.
There is technical solution used by the utility model：A kind of work being used for rotor in magneto and lower bearing assembling
Dress, including axis body, threaded joints and prismoid section with small end face and large end face, the left end of the axis body and prismoid section it is small
End face is fixedly connected, and threaded joints are fixedly connected on the circle centre position of large end face in prismoid section；
It is equipped with to be clamped the first card slot of driving plate on axis body.
Further, in the prismoid section small end face diameter be greater than or equal to axis body diameter.
Further, the axis body, threaded joints and prismoid section are integrally formed.
Further, the frock is integrally made of stainless steel.
The utility model has the advantages that：
1) rotor is prevented in assembling process, may be attracted each other caused collision with stator.Because prismoid section with
It is small―gap suture cooperation between lower bearing, so prismoid section can upwards be moved freely in lower bearing inner shaft, but can not in radial direction
Larger offset, so as to prevent the collision of rotor and stator.
It 2) being capable of guided rotor and lower bearing completion positioning.Because one end that axis body is connected with rotor, there are certain tapers
(prismoid section), the size of prismoid section large end face are more than axis body, are slightly less than the size of armature spindle socket end, although under axis body size is less than
Bearing inner race can not realize centering requirement, but can gradually be guided by prismoid section to lower bearing central to realize by rotor
Centering demand.It is since prismoid section is installed in itself with rotor in the presence of certain on axis body why to be slightly less than the size of armature spindle socket end
Position error, enough guided rotors enter lower bearing to the chamfering of the taper fit rotor tip of prismoid section.
Description of the drawings：
Fig. 1 is the assembling schematic diagram of rotor and upper and lower bearing in the prior art.
Fig. 2 is the utility model structure chart.
Fig. 3 is the utility model application structure figure.
Specific embodiment：
The utility model will be further described below with reference to the accompanying drawings.
Such as Fig. 2 and Fig. 3, the utility model discloses a kind of frock being used for rotor in magneto and lower bearing assembling,
Including axis body 11, threaded joints 12 and the prismoid section 13 with small end face and large end face, left end and the prismoid section 13 of axis body 11
Small end face be fixedly connected, threaded joints 12 are fixedly connected on the circle centre position of large end face in prismoid section 13.
For ease of pulling axis body 11, it is equipped with to be clamped the first card slot 14 of driving plate 4 on axis body 11.
The diameter of large end face is slightly less than the diameter of 200 bottom surface of rotor (i.e. armature spindle socket end) in prismoid section 13；Prismoid section 13
The diameter of middle small end face is greater than or equal to the diameter of axis body 11.
To increase the utility model intensity, axis body 11, threaded joints 12 and prismoid section 13 are integrally formed.Frock is integrally adopted
It is made of stainless steel.
In use, threaded joints 12 are threaded at 200 lower face axle center of rotor, and prismoid section 13 is placed in down
In bearing 500, the force arm of external mechanical equipment is connected with the first card slot 14, and the first card slot 14 provides the point of application.Prismoid section 13
The centering with 500 inner ring of lower bearing can be completed with guided rotor 200, and axis is dimensioned slightly smaller than due to 13 large end face of prismoid section
The size of inner ring is held, therefore prismoid section 13 itself will not generate additional assembling resistance.
The above is only the preferred embodiment of the utility model, it is noted that for the common skill of the art
For art personnel, several improvement can also be made on the premise of the utility model principle is not departed from, these improvement also should be regarded as
The scope of protection of the utility model.
